As part of its goal of producing cell-grade alumina from clay, the Bureau of Mines conducted bench-scale cyclic tests of the Bureau's proposed clay--hcl leaching--hcl sparging process and investigated in detail the crystallization of aluminum chloride hexahydrate. The composition of recycled leaching liquor was determined for two hcl sparging crystallization conditions: 36% hcl and 26% hcl. Crystallization research showed that cell-grade alumina could not be produced without a recrystallization step.
